PL/Java-related Google Summer of Code 2022 project ideas

Hello PL/Java watchers,

The participating organizations for Google Summer of Code 2022 have
been announced, and PostgreSQL will once again participate.

https://summerofcode.withgoogle.com/programs/2022/organizations/postgresql

The project ideas list for PostgreSQL can be found here:

https://wiki.postgresql.org/wiki/GSoC_2022

As in 2020 (but not last year), there are PL/Java projects included on
the ideas list.

While the PL/Java projects in 2020 were focused on the build system,
the projects for 2022 ambitiously target new functionality, building
on the work-in-progress refactoring described in pull request #399:

https://github.com/tada/pljava/pull/399

Goals of the work are a PL/Java with less functionality hard-wired in C
and more implemented in pure Java, to be more maintainable and approachable
for new developers. It will feature more complete and flexible coverage
of PostgreSQL data types (including customizable array support), and be
usable as a base for PLs in other JVM or GraalVM languages.

If you know of anyone, an "open-source beginner" 18 years or older,
meeting the "GSoC contributor eligibility" criteria described below [1],
who might be interested in the PL/Java project ideas, please consider
passing this information along.

Interested contributors can immediately begin to get familiar with
the project, building, using, and modifying it, and preparing project
proposals, which can then be submitted to GSoC during the application
period, 4 April through 19 April.

Thanks!

Regards,
-Chap
